Set includes calipers and gauges to identify external and internal threads

In addition to checking NPT and BSPT pipe sizes, use the two included gauges for measuring thread pitch.

Typically used with high-pressure brass and bronze threaded pipe fittings.

Plated with nickel, these brass fittings resist rust better than steel and unfinished brass fittings. Select them when you need more strength in corrosive environments to handle higher pressures than our low-pressure fittings.

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

Typically used with low-pressure brass and bronze threaded pipe fittings.

Also known as instrumentation fittings, these have the most precise threads and the tightest tolerances of all the brass pipe fittings we offer.

Use these fittings in extreme-pressure conditions up to 15,000 psi.

Typically used with low-pressure stainless steel threaded pipe fittings.

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

These flanges are for low-pressure applications in noncorrosive environments.

The galvanized finish on these Pressure Class 150 flanges provides fair corrosion resistance.

Made of galvanized steel, this Schedule 40 pipe has fair corrosion resistance and is designed for low-pressure applications.

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Typically used with low-pressure aluminum threaded pipe fittings.

Use these plastic fittings to connect gasoline fuel lines to machines and equipment. They have excellent corrosion resistance as well as high strength and impact resistance.

Connect these fittings to Schedule 40 plastic pipe—they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

With outlets on the side instead of on top, these manifolds have a lower profile than rectangular manifolds and fit well in cramped spaces. Use them to distribute air or fluid to three locations from a single supply source.

Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows air or fluid to follow a straight path, improving flow through your system. Also known as headers.

Fittings have sharp barbs that grip push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. Use in low-pressure hydraulic applications up to 350 psi.

Use these couplings at pressures up to 10,000 psi. The plug and socket thread together to form a stronger connection than other quick-disconnect couplings. They are compatible with High-Pressure Thread-Lock-shape plugs and sockets.

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO B-shape plugs and sockets.

Made of polypropylene, these fittings are lighter in weight than metal barbed hose fittings.

Fittings are metal for better durability than plastic barbed hose fittings. They have sharper barbs than standard barbed hose fittings to grip push-on hose without the need for clamps or ferrules. The more you pull on the fittings, the tighter the hose will grip.

Use these fittings with power washer guns and in other high-pressure water supply applications.

Compatible with ARO-shape plugs and sockets.

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.

With an unobstructed air path, these couplings have better airflow than other coupling shapes of the same size. Compatible with European-shape plugs and sockets.

Couplings allow for maximum flow because there's no shut-off valve in the plug or the socket. Compatible with Open-Flow-shape plugs and sockets.

Couplings have an identical claw-style head that connects to another twist-claw hose coupling with a quarter twist.

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

Made of stainless steel, these hose fittings are more durable than plastic barbed hose fittings and have excellent corrosion and chemical resistance. Slide the barbed end into hose and secure with a clamp.

Couplings are plastic, which is lighter in weight than metal cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Reduce the risk of spills near electronics when connecting and disconnecting liquid cooling lines. Also known as double shut-off couplings, these couplings have a shut-off valve on both sides that stops the flow of coolant if they’re separated.

The new standard for rubber hydraulic hose, this hose bends twice as sharply and resists wear and tear 80 times better than our basic hydraulic hose. The fittings come attached, so this hose is ready to connect to a male threaded fitting on one end and a female one on the other.

Hose is polyurethane so it stretches and flexes more than nylon retracting hose.

Often used in outdoor, damp, and washdown environments, these 316 stainless steel fittings will not corrode from water, salt, or chemicals. The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you won’t have to worry about matching exact threads when you’re on the job.

Made of brass, these fittings have good corrosion resistance.

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

A built-in shut-off valve stops airflow when the fittings are disconnected from tubing.

An all-metal body and built-in tube support or dual seals allow these fittings to handle the highest pressure ratings of all our push-to-connect tube fittings.

Made of EPDM, the gasket on these fittings stands up to the hot water found in heat exchangers and cooling systems. These fittings have stainless steel pipe threads, which are more durable than the plastic pipe threads found on other push-to-connect tube fittings.

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

Made of acetal, these compression fittings are lighter in weight than metal compression fittings and won’t absorb moisture when used in wet environments.

The nickel plating on these fittings provides better corrosion resistance than unplated brass fittings.

Aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Fittings have good corrosion resistance.

Lighter in weight than metal quick-disconnect couplings, these couplings are plastic.

Made of stainless steel, these fittings are more durable than plastic barbed tube fittings for food and beverage.

Made of brass, these fittings withstand frequent washdowns in food-processing applications. They also adhere to NSF/ANSI safety standards, so they’re safe to use with food, beverages, and dairy.
